Minimum RAM
  • 2 GB (4 GB or more is highly recommended)

Release Date
  • September 30th, 2015

Getting El Capitan: This is a v10.11.6 installer DMG (so no need for the combo update) straight from Apple's servers. Open it and install the package contained within, which will put the Install OS X El Capitan.app bundle into the Applications folder. You can then run it to upgrade an older version of OS X in-place or use the createinstallmedia command to create a bootable installation medium.

Thanks for creating this thread. :)

Are there any alternative browsers that people would recommend as replacements for FF 78 ESR because it's reportedly going to reach end-of-life status in October? If this is not correct then by all means, please clarify the situation! :D

  • Google Chrome 89 of March 21, is the last released for all computers and systems. This means that you will be able to browse for a few years when the support ends and Firefox will no longer work soon. Firefox's extended support is ending soon, and safari 11 hasn't received anything for a long time. The policy of the three brands of navigators in El Capitan is curious, Google has bet and put the best and will be the winner

This tip to change the date to 062112422016 in Terminal within the El Capitan installer and then restart the computer and re-attempt the installation, really should be added because otherwise you're liable to encounter (as I did recently) the following error message whilst trying to install the OS:

I seem to often have the opportunity to install El Capitan on a variety of Macs. I have not needed to use the system date change since the appearance of the latest installer from Apple. Not sure what changed, but, just reporting that I have not needed the system date change, and El Capitan simply installed without that challenge.
I don't know if that applies to all possible installs.

The download listed in the first post for the El Capitan installer appears to be the current download.

Of course, just did it. Must have forgotten when creating the thread. Sorry!

@TheShortTimer - you can now add the reset date tip for older installers :)

Done and thanks! :)

After seeing your reply, I realised what had been the source of my difficulties. I'd used an El Capitan installer which Snow Leopard had downloaded and placed into its Applications folder years ago as an upgrade option. Obviously it's an older version than the one that's now made available by Apple to download.

In the PPC forum we have threads with information on optimising and tweaking Leopard and Tiger to improve their performance - which is particularly beneficial where lower specced machines are involved. Are there any equivalent tweaks or optimisations for El Capitan in this regard?

As we're all aware, El Capitan will run with a minimum of 2GB RAM but on Macs like the 2GB MBAs where the memory is non-upgradeable, I think it would be really helpful to know what could and should be switched off in order to enjoy the best results possible and of course the information could then be added to the Wiki.

Well, one obvious one is going into accessibility and turning off transparency. IIRC it makes quite a big difference.

(But it will make El Capitan look even more ugly than it normally does...)

According to this article it definitely makes a big difference.

The results detailed in this article are very interesting.

I think that I can live with that trade-off and I honestly prefer it without the transparency effect.

Thanks. :)

A few more of these and we'll have an optimisation/tweaks category. I'll see what tips I can come up with. ;)

On Mojave, I actually prefer no transparency in conjunction with Dark Mode. I have come to live without it on my 2007 MBP and 2010 MBA (on El Cap) to lighten the load on the older GPUs too.

This is worth checking out:

It's funny that you mention Dark Mode because whilst deactivating transparency, I happened to stumble across a setting that more or less provides that appearance on El Capitan. :)

I shall indeed and thanks! :D

My early 2008 iMac still works (with El Captan) but I've read it is vulnerable to malware. I thought I could attach a new Mac Mini to it and thus at least make use of the display, but that is apparently impossible. Anyone have any suggestions?

One possible solution is to upgrade your old Mac to a more current system. I am running Ventura on my Early 2008 iMac, and works better than I first expected. A bit slow, but still a current system. You would want to make sure that you have replaced the original hard drive with an SSD, and upgraded to max Ram to 6GB. The 4GB Ram stick for that is still a bit pricey. I have not popped for that, and continue with 4GB - which is OK for the age of the iMac.
How did I get Ventura installed?
OCLP does that very well.
Target Display (where you can connect to use the iMac as an external display) did not appear until the Late 2009 iMacs, and only on 27-inch at the beginning, where you could use the thunderbolt connection for video input, and you would need another Mac that also has thunderbolt. That Target Display mode is not available on your iMac, although you could modify your iMac for video in, if you can discover how to do that. It would be major surgery on the iMac itself, I expect.

Hi, I happened to see this article, and I own an iMac 20' (2006 late) A1207. I wonder whether my iMac is able to be upgraded to OSX El Capitan? I already made a USB boot device, but when I choose to boot with the USB the iMac stays on Apple logo screen. The installer page doesn't show up.
